Latest Patents
One of Mathis's latest inventions is a processor-controlled scanning radio receiver. This device employs a microprocessor controller to operate in various modes, including a search/recall mode. In this mode, frequencies located during an automatic search operation are stored in a recirculating storage device for later user recall. The device also allows for the storage of frequencies or 'birdies' to be locked out during a search operation. The channels to be scanned are stored in an electrically alterable read-only memory, arranged in five banks with ten channels per bank. A keyboard is included, enabling users to select or deselect any one or more banks for the scanning operation.
Another significant patent is the selective rescan delay for a multi-channel scanning radio receiver. This invention features a signal-seeking scanning radio receiver that employs a selective rescan delay circuit. This circuit delays the automatic resumption of multi-channel scanning for a period following the termination of a signal on a tuned channel. It responds to an auxiliary output signal from a memory programmed to provide signals only for certain preselected channels tuned to a predetermined frequency, where two-way communications are anticipated.
